NPM Sentinel MCP Server
Community MCP server for NPM package security analysis — enabling AI agents to check npm packages for vulnerabilities, inspect package metadata, audit dependencies, and get security insights from the npm registry.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS enforced. npm registry is a trusted data source. Token security for private packages.
⚡ Reliability
Best When
An agent needs to evaluate npm package security, audit dependencies, or inspect npm package metadata before recommending or using a package.
Avoid When
You need Python, Java, or other ecosystem package security analysis — this is npm-specific.
Use Cases
- • Checking npm package vulnerabilities before installation in agent workflows
- • Auditing project dependencies for security issues from agents
- • Inspecting npm package metadata (author, maintainers, versions) for trust signals
- • Comparing package versions for breaking changes and security patches
- • Supply chain security analysis of npm dependency trees
Not For
- • Python/PyPI package analysis (npm only)
- • Deep code analysis (static analysis beyond npm audit)
- • Private npm registry packages without access
Interface
Authentication
Public npm registry is accessible without auth. NPM token required for private packages or higher rate limits. Token stored as NPM_TOKEN env var.
Pricing
Free for all public npm package analysis. MCP server is open source.
Agent Metadata
Known Gotchas
- ⚠ npm audit data may be delayed relative to NVD — CVE disclosure lag can be hours to days
- ⚠ Unauthenticated npm registry requests have aggressive rate limits — add token for production use
- ⚠ Community MCP — not official npm; may miss some registry API features
- ⚠ Scoped packages (@org/pkg) require special handling in queries
- ⚠ Deprecated packages still appear in registry — agents should check deprecation status
